US Yields Fall to Lowest This Year as Tech Slump Fuels Haven Bid

Treasuries rallied on Monday as investors flocked to the safety of US government bonds after equities slumped in a selloff driven by technology shares.

The yield on 10-year US notes fell as much as 12.5 basis points — the most intraday in almost two weeks — to 4.50%, before paring the decline. The two-year rate, which is highly sensitive to expectations for Federal Reserve policy, dropped 10 basis points to 4.17%, the lowest in over a month. Haven currencies including the yen and the Swiss franc surged.

Global markets were shaken by news of a fresh artificial intelligence model from Chinese startup DeepSeek, which raised questions over America’s technological dominance and fueled concerns that sky-high US tech valuations were unwarranted. Tech stocks plunged across the globe. European bonds also benefited from risk-aversion, with debt from Germany, Italy, France and the UK all gaining.

“It’s the by-the-book, flight to quality to the Treasury market, as risky assets plummeted,” said Chris Diaz, global fixed income portfolio manager at Brown Advisory.
